To all whom it may concern: 7 Be it known that I, OSCAR J. HAGSTROM, a citizen of the United States, residing at Berwyn, in the, county of Cook and State of Illinois, have invented certain new and useful Improtements in Combination Stop-Actions for Organs, of which the following is a s ecification.

his invention relates to combination stop actions for pipe organs, and the main ob ject thereofto provide a reliable, eflicient and improved apparatus of the class specified' characterized by simplicity, compactness and ease of manipulation. 1

Other objects and advantages secured by the invention will be apparent to those skilled in the art from the following detailed des'criptiontakenin connection with the accompanying drawings forming a part tappets an a fragment of an oscillatory rod on which it is mounted. I

Referring to the drawings, A, AHA and.

A", etc., deslgnate a series of tablets or' stop keys that are a common adjunct of any pipe organ and of which there may be, of course, any desired number. These tablets are mounted side by side, so as to be capable of independent up and down rocking or swinging movement on a stationary rod or shaft 12. The organ stops controlled by these tablets are not shown, but in this in stance they are electrically operated by circuits which are closed and opened by the engagement and disengagement of a clrcuit ma e-and-break pin 13 carried by each tablet with the circuit wires 14. When the tablet is raised, as shown in Fig. 1, the circuit is broken. When the tablet is depressed, the circuit throu h the stop-operating mechanism controlled b that tablet is established. Each tablet is controlled by a spring,

partly shown at 15, in a well known manner, the spring maintaining the tablet in either raised or. lowered position when moved tothat position. 7

. Connected to the respective tablets are a series or" oscillating rods B, B, B, B, B, etc., that are supported near their ends in a bearing strip 16 and a similar strip (not shown) on the other side of the grou of yokes shown in Fig. I and later descri ed. On eachof these rods is mounted a oup of spaced ta pets designated by b, b, b b*,'etc. eferring to Figs. 2 and 3, it will be observed that each of the rods B, B etc.: (which are allalike) is not round in cross-section, except atitsbearings in the su portin strips 1-6, but-has a substantially ha f roun side 17 and a flattened side-18 formed witha central longitudinal rib' or. ridge 19.

The tappet, as herein shown, 3

com rises a flat 813111120 that lies crosswise ef t a e flattened side of the rod, and a spring a member 21 that embacking or .cl'ampin side of the rod and is braces the half roun secured to the strip 20 by screws or rivets indicated at 22.
